Certain corals used as ornaments and for the manufacture of jewelry have become rare because of exploitation.

Answer;
-All of the above,
Genetic research and testing includes; the Human Genome Project, gene therapy
, and genetically engineering drugs.
Explanation;
-Genetic testing is a type of medical test that identifies changes in chromosomes, genes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person’s chance of developing or passing on a genetic disorder.
- Genetic research is the study of human DNA to find out what genes and environmental factors contribute to diseases. It is concerned with the study of the role of genes in traits such as the development of disease. It has a key role in identifying potential targets for therapeutic intervention and also in understanding genetically based variations in response to therapeutic interventions.
Answer:
Mutation
Explanation:
The main cause of variation within a population is usually through genetic mutation.
Mutation is the alteration of the genetic sequence within an organism. It often lead to formation of new genetic patterns and codes.
Most times, environmental influences are paramount to causing genetic mutation within a population.
Other times, it might be due to competition and some other internal factors.
Mutation can be transferred from parents to offspring in most cases.
Heterozygous straight (F) x heterozygous bent (f)
________
<u>|FF | Ff |</u>
<u>|Ff | ff |</u>
That means 1/4 will be 100% straight
2/4 will have straight with a recessive trait of bent
1/4 will be recessive recessive which means bent
So out of 4 chimpanzees, 1 of them will have bent.
Hope this is what you wanted help with. :)
I would say B, <span>differ greatly between single solar systems. As we all know, I believe this is the only planet with life, but there might be many out there, too. Each planet should have very different characteristics unlike ours. So it may vary.</span>
